Electromotive Ignition Wanted, HPX or HPV

[4.6 MGB V8]

I am looking for an Electromotive HPX or HPV four coil ignition controller for a V8 project. This is the stand alone system that consists of a coil pack and built in ignition controller, not the newer XDI system with the full ECU.
I would prefer a NOS or working used module but I will consider any used, incomplete or even broken system.
Any information or leads would be appreciated.
Thanks
